' In Mexico April 9, 1937 '2 Claims.

This invention relates to means for feeding washers to the pins of molds employed in the manufacture of rubber heels, and it consists in the constructions, arrangements, and combinations herein described and claimed.

It is an object of the invention to provide a washer feeding device of simplicity in construction and operation and one in which the washers are fed to the pins of a mold regardless of the varying height of the pins as well as varying inclinations which the pins may have.

It is a still further object of the invention to provide a washer feeding device in which a washer magazine is provided, and in which the washers are individually placed in position upon the pins.

Additional objects, advantages and features of invention will be apparent from the following description considered in conjunction with the accompanying drawing, wherein Figure 1 is a vertical sectional view through the washer feeding device.

Figure 2 is a fragmentary sectional view of the device in use.

Figure 3 is a fragmentary plan view of a series of molds indicating the positions of the pins.

Figure 4 is a front elevation of the magazine and feed guide.

Figure 5 is a rear elevation thereof.

Figure 6 is a bottom plan view of the guide.

There is illustrated in Figures 1 and 2, a tool generally indicated at I0, comprising an angularly disposedhandle II, the lower end of which mounts a guide block I2. Upon the underside of the handle II there is screw-threadedly engaged a shank I3, extending substantially at right angles to the handle, and upon the shank there is revoluble a hand grip I4. In' order that the hand grip I4 may be free of vibrations and have the necessary flexibility, the grip has an axial bore I5 within which a piston I6 is reciprocable, the latter being secured to the shank I3 adjacent its lower end. A helical spring I! is interposed between the piston and a washer I8 seated upon the base of the bore. From the foregoing, it will be seen that the hand grip is resiliently mounted and free from undue vibrations or shocks which might be imparted due to encountering pins of the molds, as will be more clearly apparent as the description proceeds.

The guide I2 has an aperture I9 extended vertically therefrom and fixed securely therein, there is a tubular sleeve 20, adapted to receive a tubular magazine sleeve 2|. The sleeve 2| is open at its upper end to receive washers 22 arranged in superposed relation, as may be seen in Figure 2, retained in such position by engagement of the lowermost washer upon a ledge 23. As may be seen in Figure 6, the ledge is bifurcated by a slot 24, permitting passage of the upper ends of pins 25 and preferably the ledge 23 is of a height permitting the pins to project thereabove so as to engage the apertures of the washers when drawn thereacross.

The guide I2 comprises an entrance opening 21 at its rear face, tapering in the direction of the bifurcation 24 serving to guide the pins so as to align the upper ends of the pins with the apertures of the washers. The front end of the guide I2 has a transversely extended slot 28 of a diameter to permit passage of the washers therethrough and the-upper edge of the slot may be recessed as at 29 to permit passage of the upper ends of the pins therethrough.

In use, with the pins 25 arranged within the heel molds indicated at 3B in Figure 3, the device is grasped by the handle I 4, the guide I2 being aligned with the rows of pins 25 so as to admit the pins through the entrance opening 21. The device will be held in the position shown in Figure 2, and obviously, the upper end of the pins will be guided by the bifurcation 24 so as to encounter the aperture of the lowermost washer within the magazine 2|. The contact between the pins and washers will be more or less abrupt to effect withdrawal of the washers, but shock or unsteadying effect will not be imparted to the operator due to the resilient hand-grip mounting.

While we have shown and described a preferred form of the invention, this is by way of illustration only, and we consider as our own, all such modifications in structure as fairly fall within the scope of the appended claims.

We claim:

1. A washer feeding device for pins of molds comprising a body member having a pin entrance slot extending longitudinally thereof and opening upon the bottom wall thereof, said body having a vertically extended opening, a ledge on the body member beneath the opening, said ledge having a furcation extended in the direction of the slot and opening thereupon, a sleeve fixed in the vertical bore, a washer magazine engaged within the sleeve for discharge of washers upon the ledge, the sides of the entrance slot of the guide tapering in the direction of the ledge, a handle on the body member extending rearwardly of the entrance slot, the handle having a downwardly extending spindle, and a resiliently mounted hand grip on the spindle.

2. The structure of claim 1 in which the hand grip includes a bore, a piston fixed to the spindle adjacent the free end and reciprocable therein, and a helical spring on the spindle interposed between the piston and the base of the bore.
